Key Features

The ACT 4 Pad Rigid Race Disc incorporates several advanced features to optimize performance and longevity:

• Constructed with high-grade ceramic friction materials that withstand extreme heat and stress, ensuring consistent performance during demanding driving conditions.
• Four-pad rigid design provides a more aggressive engagement compared to stock discs, ideal for racing applications where quick shifts and minimal slippage are critical.
• Top-grade rivets securely fasten the friction material to the disc, enhancing strength and reducing the risk of delamination under high torque loads.
• Carefully selected rivet design and materials maximize durability and ensure the disc maintains integrity during intense use.
• Lightweight construction with a product weight of approximately 1.9 lbs. helps reduce rotational inertia, contributing to improved throttle response.
• Designed to fit the original clutch assembly without modifications, ensuring a straightforward installation process.
• Meets SFI 1.1 specifications, making it suitable for sanctioned racing events and high-performance applications.
• Optimized for smaller disc sizes in high-revving engines, providing a balance of aggressive engagement and reliability.

Construction & Design

The ACT 4 Pad Rigid Race Disc features a meticulously engineered design that combines durability with high-performance capabilities. The core of the disc is made from a high-strength steel hub that provides a solid foundation for the friction material. The ceramic friction pads are bonded to the disc using advanced rivet technology, ensuring they remain securely attached even under extreme conditions. The rivets themselves are crafted from top-grade materials to withstand the intense heat generated during aggressive driving.

The rigid four-pad configuration eliminates any floating or dampening mechanisms found in stock discs, resulting in a more direct and responsive clutch feel. This design choice enhances the transfer of power from the engine to the drivetrain, making it especially beneficial for racing scenarios where every millisecond counts. The disc's lightweight construction reduces rotational mass, which can contribute to quicker engine response and improved acceleration.

Installation & Fitment

The ACT 4 Pad Rigid Race Disc is a direct replacement for the factory clutch components in the specified Toyota Supra models. Installation is straightforward for those familiar with clutch assembly procedures, as it uses the original mounting points and hardware. No modifications, cutting, or special tuning are required to install this race disc, making it an excellent upgrade for racers and enthusiasts alike.

• Simply remove the existing clutch disc and replace it with the ACT 4240007 for improved performance.
• Ensure proper torque specifications are followed during installation to maintain optimal clutch operation.
